An Investigational Scan (rh PSMA 7.3 PET/MRI) for the Detection of Recurrent Disease and Aid in Radiotherapy Planning in Biochemically Recurrent Prostate Cancer
A Prospective Pilot Study Investigating rhPSMA 7.3 PET/MRI in Detecting Recurrent Disease and Aid in Radiotherapy Planning in Patients With Biochemically Recurrent Prostate Cancer

Detailed Description
PRIMARY OBJECTIVE:
I. To evaluate the positive predictive value and detection rate of fluorine F 18 rhPSMA-7.3 (F-18 rhPSMA-7.3) positron emission tomography (PET)/magnetic resonance imaging (MRI) in detecting recurrent disease in prostate cancer patients with biochemical recurrence.
SECONDARY OBJECTIVE:
I. To determine the change in salvage radiation treatment plan after F-18 rhPSMA-7.3 PET/MRI imaging.
EXPLORATORY OBJECTIVES:
I. To assess the feasibility of utilizing the PSMA avid recurrent disease on PET/MRI as an alignment tool for MR guided radiotherapy (MR linear accelerator [MR-LINAC]).
II. To assess the treatment response in those patients who demonstrate rhPSMA-7.3 avid disease on the first PET/MRI scan.
OUTLINE:
Patients receive F-18 rhPSMA-7.3 intravenously (IV) and after approximately 60 minutes of uptake time, will undergo PET/MRI over 60 minutes. Patients with evidence of F-18 rhPSMA-7.3 disease in the first PET/MRI scan undergo a second F-18 rhPSMA-7.3 PET/MRI at 6 months after the second dose of standard hormonal therapy.
After completion of study treatment, patients are followed up within 7 days.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Positive predictive value (PPV) of F-18 rhPSMA-7.3 positron emission tomography/magnetic resonance imaging (PET/MRI) in detecting recurrent disease
Time Frame: Up to 6 months
|
Will be evaluated on both a per-patient and per-region basis.
Will estimate the PPV rate and corresponding 95% confidence interval.
|
Up to 6 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Detection rate
Time Frame: Up to 6 months
|
Defined as the proportion of patients with prostate-specific membrane antigen (PSMA) positive results.
The association between detection and prostate specific antigen level will be assessed by Wilcoxon rank-sum tests.
|
Up to 6 months
|
Change in salvage radiation treatment plan
Time Frame: Baseline up to 6 months
|
The proportion of patients with major and minor changes will be summarized.
